TILE=CUTTING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 398,885, dated March 5, 1889.

Application filed February 20, 1888- Serial No. 264,610. (No model.) Patented in Germany September 28, 1887, No. 44,518; in Belgium January 31, 1888.11'0. 80,241,and,i11 France March 26, 1888, No. 188,107.

T0 to whom it may concern/.-

Beit known that I, CARL ALBERT EISSNER, a subject of the Emperor of Germany, and a having a shape of periphery as Figs. 3, i, 5,

resident of Lugamin Saxony,Germany, have invented an lmprovem ent in Machin cs for Cutting Clay in the M an uf actu re of Bricks and Tiles and for Like Purposes, (for which I have obtained Letters Patent in the followin countries, namely: Germany, No. 44,519, dated.

September 28, 1887 lfrance, No. 18$,l07, dated March 26, 1888, and in Belgium, No. 803% dated January 31, 1839,) of which the following is a specification.

This invention relates to the cutting into equal or n-edetermined lengths such material as clay fed from a brick-press, and other material fed continuously with equable or varyin g velocity.

The improvement consists, first, in the'manner of and direct means for actuating the cutters, and, secondly, in the mechanism or gear by which the movement of the material sets the actuating mechanism in motion, so that the cutting of the material is rendered dependent on the feed movement thereof.

or 6, according to the shape of section of the blank to be cut, are carried upon shafts journaled so that the superficial friction of the drum or drums on the advancing blank causes the rotation of the drums. On the shaft of one of the drums is a miter-wheehm, gearing into a similar miter-wheel, m, on the shaft m On the shaft m are fixed two tumblers, o 0, adapted as the shaft rotates to rise under and lift levers or arms e, connected with the steam inlet and outlet ports 1) and i f, respectively, in connection with one end of tion of the blank controls the operation of the Referring to the accompanying drawings illustrating the invention as applied to the cutting of oblong and circular sections, Figure 1 shows the material, a, issuing from the tube 0 of the brick-press.

Fig. 2 shows in side elevation the cutters and mechanism for larged elevational view of one of the biston- 5 blank.

valves.

The cutters consist of wires or doubleedged knives, and there may be one or more cutters. The said cutters are fixed between the arms of a bow-frame, 7;, having a downward extension pit'oted on a rocking shaft or pin, the depth of said bow-fra me being sufticient to permit of free passage of the matecutters, the blank is cut into equal or predetermined lengths without necessitati n steady feed of the blank. It is therefore of great advantage with hand-presses.

The diameter of the friction-drums Z9 determine the length of the blank cut at each passage; or, if more than one cutter, being fixed in the bow 7a, the aggregate length of the sections cut off at each passage of the cutter. The blank is supported by rollers so arranged as to permit of the passage of the cutters between them. The cutter-operating machinery may likewise be set in action by mechanism controlled by a block or other object carried forward with or by the advancing I claim The combination, with a bow, 7;, carrying cutters, of a cylinder, 1, having inlet-"alves p p and outlet-valves ff, a piston in said cylinder having rod q u, adapted to move said bow in back and forth, friction-drum b, and tumblers 0 o o 0 revolved by gear from said drum, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
